Cryotherapy is commonly used by athletic trainers, although evidence is inconsistent to support its usage. Data are also lacking as to how athletic trainers treat common injuries with cryotherapy. The purpose of this study was to ascertain how collegiate athletic trainers approach the use of cryotherapy and whether that usage reflects what little we know about the modalities. Survey results indicated great variability in respondents’ approaches to the treatment of an acute and subacute ankle sprain. Additional data are needed to create clear treatment guidelines with respect to cryotherapy. Certain aspects of the application of cryotherapy should be reviewed and use adjusted accordingly.

Cryotherapy is a common therapy used by allied health care professionals to treat orthopedic injuries 1 and to manage acute musculoskeletal injuries. 2 Purported benefits of cryotherapy include minimizing inflammation, edema, hypoxic injury, and soft-tissue damage, as well as reducing muscle

For decades, cryotherapy has been a popular modality for

One of the purported benefits of cryotherapy is the ability of this therapeutic modality to induce analgesia. 1 , 2 Cryotherapy is, therefore, regularly used as an immediate treatment for pain relief following acute injuries, potentially allowing athletes who incur minor sprains or contusions to

If ankle joint cryotherapy impairs the ability of the ankle musculature to counteract potentially injurious forces, the ankle is left vulnerable to injury.
To compare peroneal reaction to sudden inversion following ankle joint cryotherapy.
Repeated measures design with independent variables, treatment (cryotherapy and control), and time (baseline, immediately post treatment, 15 minutes post treatment, and 30 minutes post treatment).
University research laboratory.
Patients or Other Participants:
Twenty-seven healthy volunteers.
An ice bag was secured to the lateral ankle joint for 20 minutes.
Main Outcome Measures:
The onset and average root mean square amplitude of EMG activity in the peroneal muscles was calculated following the release of a trap door mechanism causing inversion.
There was no statistically significant change from baseline for peroneal reaction time or average peroneal muscle activity at any post treatment time.
Cryotherapy does not affect peroneal muscle reaction following sudden inversion perturbation.

Despite recent findings regarding lower extremity function after cryotherapy, little is known of the neuromuscular, kinetic, and kinematic changes that might occur during functional tasks.
To evaluate changes in ground-reaction forces, muscle activity, and knee-joint flexion during single-leg landings after 20-minute knee-joint cryotherapy.
1 × 4 repeated-measures, time-series design.
Patients or Other Participants:
20 healthy male and female subjects.
Subjects performed 5 single-leg landings before, immediately after, and 15 and 30 minutes after knee-joint cryo-therapy.
Main Outcome Measures:
Ground-reaction force, knee-joint flexion, and muscle activity of the gastrocnemius, hamstrings, quadriceps, and gluteus medius.
Cryotherapy did not significantly (P > .05) change maximum knee-joint flexion, vertical ground-reaction force, or average muscle activity during a single-leg landing.
Knee-joint cryotherapy might not place the lower extremity at risk for injury during landing.

To examine the effects of a whole-body cryotherapy (WBC) protocol (3 min at –110°C) on acute recovery and key variables of endurance performance during high-intensity intermittent exercise in a thermoneutral environment.
Eleven endurance athletes were tested twice in a randomized crossover design in which 5 × 5 min of high-intensity running (HIR) were followed by 1 h of passive rest at ~22°C, including either 3 min of whole-body exposure to –110°C (WBC) or a placebo intervention of 3 min walking (PBO). A ramp-test protocol was performed before HIR (R1) and after the 1-h recovery period (R2). Time to exhaustion (t lim) was measured along with alterations in oxygen content of the vastus lateralis (TSI), oxygen consumption (VO2), capillary blood lactate, heart rate (HR), and rating of perceived exertion (RPE) during submaximal and maximal running.
The difference in t lim between R1 and R2 was lower in WBC than in PBO (P < .05, effect size d = 1.13). During R2, TSI was higher in WBC during submaximal and maximal running (P < .01, d = 0.68−1.01). In addition, VO2, HR, and RPE were lower at submaximal level of R2 after WBC than in PBO (P = .04 to <.01, d = 0.23−0.83).
WBC improves acute recovery during high-intensity intermittent exercise in thermoneutral conditions. The improvements might be induced by enhanced oxygenation of the working muscles, as well as a reduction in cardiovascular strain and increased work economy at submaximal intensities.
